2 CAUTIONS ON INSTALLATION
Noise or disturbance of the picture may be generated if this unit or
any other electronic equipment using microprocessors is used near a
tuner or TV.
If this happens, take the following steps:
l
install this unit as far as possible from the tuner or TV.
l
Set the antenna wires from the tuner or TV away from this unit's
power cord and input/output connection cords.
l
Noise or disturbance tends to occur particularly when using indoor
antennas or 300 Q/ohms feeder wires, We recommend using
outdoor antennas and 75 Q/ohms coaxial cables.

3 CAUTIONS ON HANDLING
l
Switching the input function when input jacks are not
connected
A clicking noise may be produced if the input function is switched
when nothing is connected to the input jacks. If this happens,
either turn down the MASTER VOLUME control or connect
components to the input jacks.
l
Muting of PRE OUT jack, HEADPHONE jack and SPEAKER
terminals
The PRE OUT jack, HEADPHONE jack and SPEAKER terminals
include a muting circuit. Because of this, the output signals are
greatly reduced for several seconds after the power operation
switch is turned on or input function, surround mode or any other
set-up is changed.
If the volume is turned up during this time, the output will be very
high after the muting circuit stops functioning. Always wait until
the muting circuit turns off before adjusting the volume.

4 FEATURES
1. DolbV Pro Logic II decoder
Dolby Pro Logic II is a new format for playing multichannel audio
signals that offers improvements over conventional Dolby Pro
Logic. It can be used to decode not only sources recorded in
Dolby Surround but also regular stereo sources into five channels
(front left/right, center and surround left/right). In addition, various
parameters can be set according to the type of source and the
contents, so you can adjust the sound field with greater precision.
2. DolbV Digital decoder
Dolby Digital, a digital discrete system in which the different
channels are completely independent, recreates "three-
dimensional" sound fields (sounds with a sense of distance,
movement and position) with no crosstalk between channels for
greater reality. In addition, the 5 channels (excluding the 0.1
channel for low frequency effects) have a playback range
extending to 20 kHz, the same as the range of CDs, thus resulting
in clearer, more richly expressive sound.
3. DTS (Digital Theater SVstems)
DTS provides up to 5.1 channels of wide-range, high fidelity
surround sound, from sources such as laser disc, DVD and
specially-encoded musrc discs.
l
Whenever the power operation switch is in the STANDBV
state, the apparatus is still connected on some AC line-
voltages.
Please be sure to unplug the cord when Vou leave home for,
saV, a vacation.
4. High performance DSP simulates 7 sound fields
Playback IS possible in 7 surround modes: 5-channel Stereo, Mono
Movie, Rock Arena, Jazz Club, Video Game, Matrix and Virtual.
You can enjoy a variety of sound effects for different movie
scenes and program sources even with stereo sources not in
Dolby Surround.
5. Personal Memory Plus function
Personal Memory Plus is an advanced version of Personal
Memory. With Personal Memory Plus, the set automatically
memorizes the surround mode, channel volume, surround
parameters, etc., for each of the separate input sources.
6. Remote control unit with pre-memory function
This unit comes with a remote control unit equipped with a pre-
memory function. The remote control command codes for
DENON remote controllable AV components as well as for LD
players, video decks, TVs, etc., of other major manufacturers are
prestored in the memory.
7. 6CH EXT. IN jacks
This unit is equipped with 6CH EXT. IN jacks for use with audio
formats of the future.
